Bulletin 140MG

Allen Bradley Bulletin 140MG

The Allen-Bradley Bulletin 140MG series consists of protection circuit breakers for motors. These breakers are intended for efficient short-circuit and overload protection. These breakers also provide precise control for the connected motor while ensuring reliable protection for industrial applications. They are small, with high interrupting capacities and adjustable trip settings that allow them to fit into any automation system. The Bulletin 140MG series improves equipment safety and system reliability by preventing motor damage and reducing downtime.
